Step-by-step explanation:
The ratio of hot sauce to BBQ sauce is 3 mL to 2 spoonfuls (9 to 6 simplifies to 3 to 2 because the fraction 9/6 = 3/2).
Look for any answers that simplify to this 3 to 2 ratio:
B. 3 mL to 2 spoonfuls
C. 45 mL to 30 spoonfuls: 45/30 = 3/2 (divide both terms by 15)
E. 12 mL to 8 spoonfuls: 12/8 = 3/2 (divide both terms by 4)

Answer:
Correct!
Step-by-step explanation:
First, I'll try to solve it myself.
2(2a-1)+3a=7a-2
7a-2
4a-2=7a-2
His is very correct!
